School Library Journal Gr 3-5ÄA unique book on the author's personal experiences with mud. Dewey offers good information on quicksand, primordial ooze, adobes, etc., and describes finding a fossilized bone of a Camalops, a sort of prehistoric, humpless camel. Full-color photographs and black-and-white drawings appear throughout. However, the writing gets so bogged down in dialogue that most youngsters will have a difficult time wading through it to get to the facts. Another problem is accessibility. Students researching the Zuni and their Mudheads, the nest-building techniques of wasps, or the Rio Grande will probably not think to look in this book. An appended list of plants and animals named after mud could prove handy, but the glossary, which includes words such as muddle and muddlehead, seems to be of marginal relevance. Students seeking material on the subject should look to Peter Goodwin's Landslides, Slumps, & Creep (Watts, 1997). Mud Matters will find little use in libraries.ÄAnne Chapman Callaghan, Racine Public Library, WI
